| Let Jξ(z) denotes the Bessel function of the first kind of order ξ. For three different kinds of normalizations of Nξ(z)=az2Jξ″(z)+bzJξ′(z)+cJξ(z), we find the radius for Ma–Minda classes: S∗φ-radii and Cφ-radii. We further establish the radii of γ-spirallike of order α and convex γ-spirallike of order α of these normalized functions. As an application of our results, we derive sufficient conditions for the Nξ(z) to be a member of the unified subclasses of starlike and convex functions. The obtained radii are sharp. |
